..ELEVATED RISK FOR FIRE SPREAD TODAY
THERE IS AN ELEVATED RISK FOR FIRE SPREAD TODAY ACROSS PORTIONS OF
EASTERN PENNSYLVANIA. MINIMUM RELATIVE HUMIDITY VALUES WILL DROP
TO AROUND 25 TO 35 PERCENT THIS AFTERNOON. THIS WILL BE
ACCOMPANIED BY TEMPERATURES RISING GENERALLY RISING INTO THE 70S

CONDITIONS IMPROVE DURING THE EVENING AS THE WIND DIMINISHES AND
THE RELATIVE HUMIDITY INCREASES.
OUTDOOR BURNING IS STRONGLY DISCOURAGED. BE SURE TO PROPERLY
EXTINGUISH OR DISPOSE OF ANY POTENTIAL IGNITION SOURCES, INCLUDING
SMOKING MATERIALS SUCH AS CIGARETTE BUTTS. USE CAUTION WHILE USING
ANY MACHINERY OUTDOORS, SUCH AS LAWN CARE EQUIPMENT, THAT COULD
CAUSE SPARKS TO COME IN CONTACT WITH THE DRY GROUND.
THIS FORECAST CONSIDERS METEOROLOGICAL, FUEL, AND LAND CONDITIONS
AND HAS BEEN DEVELOPED IN COORDINATION WITH STATE FIRE OFFICIALS.
